Maintenance of elevator hall doors and car doors. Elevator malfunctions usually occur on the elevator hall and car doors, so attention should be paid to the maintenance of the hall and car doors. One is to refuel the fuel on the upper sill of the door and keep it in good condition, so that the elevator will not make unpleasant noises during operation and the opening of the door. Pay attention to the inspection of the safety contact plate or light curtain type contact plate switch wire of the elevator, as the frequency of opening and closing the door in the elevator is high, which can cause damage to the switch wire. This requires maintenance personnel to inspect it every time they work,FoggiaHousehold duplex small elevator, and replace it in advance to avoid users having doubts about the quality of the elevator product due to door issues.The effective support width of the upper and lower support beams should be greater than the width of the escalator truss, and there should be embedded steel plates.Foggia,Factors to consider when choosing a household elevator: . Safety. Generally, brand elevators must have third-party testing, and elevators that have been inspected by professional organizations are safe, reliable, and guaranteed to be used with peace of mind. In addition, when choosing to purchase villa elevators, it is important to understand the safety components and configuration of this elevator. The essential safety equipment in the villa elevator includes a backup power supply and an emergency call outside telephone system to ensure the safety of private users on the elevator.The compensation chain and rope shall not collide with the shaft or other components during the operation of the elevator.Vukovar,The beam edge distance is too small: The method of shortening the lower platform is to shorten the total length of the escalator, but note that the range of shortening is very limited, generally not exceeding mm. Generally, the platform cannot be shortened because it contains equipment such as cabinets and motors. Change the angle of the escalator from degrees to degreesThe compensation chain and rope shall not collide with the shaft or other components during the operation of the elevator.During the use of elevators, some elevator users seek temporary workers or unqualified companies for elevator maintenance in order to reduce costs and save funds. Once safety issues arise, even the responsible unit cannot be found. If the maintenance is carried out by elevator manufacturers or qualified professional companies, on the one hand, the maintenance technology and quality are guaranteed, and on the other hand, if any problems occur, when instructed by the fire center or the dedicated operation button of the first floor firefighter to enter the firefighting state, the elevator should immediately stop on the floor without opening the door, return to the first floor station, and automatically open the elevator door if it is in the upward direction.The braking system of the elevator is usually closed, which means it is in the braking state when there is no power, and only when it needs to be turned on,FoggiaFixed lifting rotating stage, will the power turn on the brakes. So as soon as there was a power outage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, cut off the power and the elevatorMeasurement of elevator shafts in new construction projects under different on-site conditions: When the building design is not yet completed, the operator only needs to provide the user with the standard elevator layout of the required elevator specifications, and the user entrusts the design department to design the elevator shaft. When the architectural design has been completed, and the site has not yet been constructed, is under construction or has been completed, it must be determined based on the current construction or measured dimensions. If the original civil design of the shaft needs to be modified, the user should entrust the architectural design department to make the shaft design modification based on the layout provided by the elevator.Inspection items,During the use of elevators, some elevator users seek temporary workers or unqualified companies for elevator maintenance in order to reduce costs and save funds. Once safety issues arise, even the responsible unit cannot be found. If the maintenance is carried out by elevator manufacturers or qualified professional companies, on the one hand, and on the other hand if any problems occur, someone is also responsible.The call button on each floor is no longer working, and the call is cut off.The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.

If the elevator is in a downward direction, immediately close the door and return to the first floor station, and automatically open the elevator door.Where is good,When the normal power supply is cut off, the lighting inside the non fire elevator has no power, while there is still lighting inside the fire elevator.Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.The mechanical components of the elevator's traction machine require oil. There are two scales on the outer cover of the traction machine. Open the oil nozzle to check that the oil should be in the middle of the two scales. If the oil is lower than the lower scale, it means that the traction machine should be refueled. If not refueled the elevator will not operate well for a long time, leading to the burning of the elevator traction machine and motor. After the elevator has been running for a long time, the oil should be replaced in a timely manner to keep the traction machine clean and in good condition.Foggia,The door closing button has no self maintenance function. During the designated maintenance period, the elevator components in operation are inspected, dust is removed, and safety devices are debugged. Including non-destructive testing and maintenance of elevator traction steel wire ropes.The requirement for the shaft is that it should not be plastered which is beneficial for reducing noise, but there should be no protruding foreign objects.b. When the old elevator cannot start: due to the inability to enter the shaft, limited data can only be obtained from outside the shaft to determine whether it is non-standard (if there is a high platform in the machine room, but it is not accurate enough) for elevator quotation negotiation reference. In this case, the signing of the contract should state that the shaft rectification and costs are the responsibility of the user. For uncertain shaft structures and dimensions, users should be reminded to provide them to the elevator after the old elevator or notify the elevator to take measurements before the new elevator is put into operation.
